I cone 6 and also an annular tapering space or chamber around the sides of the pan. The handles 15 of the pan are applied to the inside thereof, so that they may be readily reached to lift the pan and may not interfere with the application of the pan to the casing or of the cover to the pan. A cover 18 neatly fits the pan. This cover may have a thermometer 19 suitably attached, so as to indicate with approximate accuracy the temperature within the pan. A handle serves to lift the cover from the pan.

When the parts are in operative position, with lamp 5 lighted, the hot air from the lamp rises through holes 1 and is deflected by cone 6, so that it rises against the sides of the I an. Direct radiation of heat from the cone 6 reaches the bottom of the pan. Heat rising round the sides of the pan may escape i through holes 11 to prevent excess of heat The casing A is of sheet metal, preferably l round the pan. Fresh air enters the casing tinned. T he lower portion 1 is a hollow cylinthrough holes 2 and is heated by the lamp. der having side openings 2 2 for the admission What I claim is of air. This cylindrical portion of the casing 1.

To all whom it may concern:

Be it known that I, MAY BURGESS, a citizen of the United States, residing at Green I Bay, in the county of Brown and State of Wisconsin, have invented certain new and useful Improvements in Dough-Raisers, of which the following is a specification, reference being had therein to the accompanying drawings.

This inventionrelates to heaters especially intended to raise bread by means of the heat of a lamp. I

The invention consists in certain constructions and combinations, substantially as hereinafter pointed out and claimed.

Figure 1 is a side elevation of the heater with cover in place for use. Fig. 2 is a vertical central section with cover slightly lifted. Fig. 3 is a central section of pan at a right angle to the position of the pan in Fig. 2.
